Abstract (en)
[origin: WO2021168244A1] An apparatus for controlling a thickness of a crystalline ribbon grown on a surface of a melt includes a crucible configured to hold a melt; a cold initializer facing an exposed surface of the melt; a segmented cooled thinning controller disposed above the crucible on a side of the crucible with the cold initializer; and a uniform melt-back heater disposed below of the crucible opposite the cooled thinning controller. Heat is applied to the ribbon through the melt using a uniform melt-back heater disposed below the melt. Cooling is applied to the ribbon using a segmented cooled thinning controller facing the crystalline ribbon above the melt.
